Full Stack Developer
AI Search and Marketing Intelligence Platform
Portugal remote friendly
We are supporting an early stage AI company building a platform that helps global brands understand and influence how they are recommended by large language models such as ChatGPT, Gemini, and Perplexity.
The product analyses real LLM responses at scale, identifies where recommendations originate across sources like Reddit, YouTube, publishers, and Amazon, and automates actions that measurably improve brand visibility, cost efficiency, and revenue attribution.
The company already works with well known international consumer brands and agencies and is expanding its engineering team as the platform scales.
The Role
This is a hands on full stack role joining an established but still early engineering team.
You will work across a data heavy web platform that combines ingestion pipelines, AI driven scoring, and interactive dashboards with automated execution layers.
You will collaborate closely with senior backend and frontend engineers, data specialists, and technical leadership, with real ownership over how features are designed and delivered.
What You Will Be Doing
Building interactive dashboards and tools using React and Next.js to visualise AI and brand intelligence data
Developing backend services, APIs, and core data models using TypeScript and Node.js
Working with PostgreSQL and an ORM such as Prisma
Integrating with LLM APIs and processing large volumes of structured and unstructured data
Supporting workflows that score, classify, and prioritise brand actions across multiple channels
Writing reliable, production ready code with appropriate test coverage
Contributing to cloud deployments, CI CD, and platform scalability
Using AI assisted or agentic coding tools as part of your daily development workflow
What We Are Looking For
2 to 5 years experience as a full stack developer in a SaaS or startup environment
Strong experience with React, Next.js, TypeScript, and Node.js
Experience building data rich applications and APIs
Solid understanding of relational databases, ideally PostgreSQL
Exposure to AWS or similar cloud platforms
Practical curiosity about AI systems and comfort using AI tools to improve development velocity
Nice to Have
Monorepo experience such as Turborepo or pnpm workspaces
Docker or containerised deployments
Experience working with LLM orchestration or experimentation frameworks
Observability, logging, or performance monitoring tools
Data pipeline, scraping, or ingestion experience
Why Consider This Opportunity
Early engineering role on a genuinely new applied AI category
Work on real production systems used by global brands
Strong technical leadership with prior MarTech and data platform experience
High ownership, low bureaucracy, and meaningful product influence
Competitive salary and early stage equity
Flexible working with preference for Portugal based candidates
